DetailsThese HI-SPEED variators are Polini’s newest development for the 50cc engines. They are of high quality and feature an optimised ramp design. Depending on the model, the kit usually includes a torque spring that prevents belt slip and thus ensures better power transmission. The really cool thing is, however, the evo slider, a kind of guide plate that tackles the problem of twisting torque springs. Depending on which kit you get, there may also be a set of reinforced clutch springs included that will make the clutch engage at higher revs taking into account the extended transmission range.
